MATba Rofex is Argentina's leading derivatives exchange, formed in 2019 through the merger of the Buenos Aires Cereals Market (MATba, founded 1907) and the Rosario Futures Exchange (Rofex, founded 1909). As Argentina's primary exchange for agricultural commodity futures, it trades soybeans, corn, wheat, sunflower seed, and soybean products alongside financial futures including US dollar, sovereign bonds, and equity index contracts. MATba Rofex is critical for Argentine agribusiness hedging, as Argentina is one of the world's top soybean exporters.

The Chicago Climate Exchange (CCX) was North America's first and only voluntary, legally binding greenhouse gas emission reduction and trading system. Founded in 2003 by economist Richard Sandor, CCX allowed member companies to make binding commitments to reduce carbon emissions and trade Carbon Financial Instruments (CFIs). Acquired by ICE (Intercontinental Exchange) in 2010, CCX ceased operations the same year after voluntary carbon credit prices collapsed following the failure of US cap-and-trade legislation.
